rtc: Disable EFI rtc for x86
commit da167ad7638759 ("rtc: ia64: allow other architectures to use EFI
RTC") inadvertently introduced a regression for x86 because we've been
careful not to enable the EFI rtc driver due to the generally buggy
implementations of the time-related EFI runtime services.
In fact, since the above commit was merged we've seen reports of crashes
on 32-bit tablets,
https://bugzilla.kernel.org/show_bug.cgi?id=84241#c21
Disable it explicitly for x86 so that we don't give users false hope
that this driver will work - it won't, and your machine is likely to
crash.
